Thanks for the dicussion contribution.
What is the interface requirement between heterogeneous processes?
The rules language has the ability to dispatch data streams to many
OPES services, not must SMTP. It must be able to specify which
messages go to which services.
The rules may be also be invoked on data returning from an OPES service.
Each rule is a condition and an action. If the condition is met
then the action is invoked. Your note seems to focus only on
parameters that are part of the action, as if the condition tests
didn't exist. Or perhaps I'm misunderstanding you.
